Application tiled September 24, 1883. (Nomodcl.)

To all whom, t may concern:-

Be it known that L'LOUis PETER BOUVIER,

of the city of Toronto, in the county of York,

" inthe Province of Ontario, Canada, machinist,

' 5 have invented certain new and useful Improvements in Envelope-Machines; and I do hereby declare that thefollowing is a clear, full, and exact description of the same.

The object of the invention is to producean [o envelope-machine which will gum, fold, and

finish the greatest possible number of envelopes with the least possible j ar on the machine; and it consists, essentially, in arranging the p gumming and picking-up mechanism in the I manner hereinafter explained.

Figure 1 is a perspective view of a portion of the machine, showing the gum-dishes, gumniing-rollers, and other mechanism for gumming or pickingup the blank. Fig. 2is averti- 2O cal longitudinal erosssection of the complete machine. Fig. 3 is a perspective detail showing the blanks with posts for holding them -in position. Fig. 4 is a perspective detail of one of the front posts, showing its spring. Fig.'

5 is a perspective detail, showing ya bottom `view of the. gum-dish, which is situated over the pile of blanks, and exhibiting the springs arranged to throw the blank ofi' the picker. Fig. 6 is a detail of the cam mechanism and 3o. pitman for operatingthe picker. Fig. 7 is a detail showing the .pitman and cam for operating the distributingroller. Fig. 8 is a detail show-in g the mechanism for operating the aux-4 iliary gummer. Fig. 9 is aside elevation of the machine, showing the various operating parts in connection with the main drive-shaft.

" Fig. 10 is a perspective showingthe pickers and the mechanism for. operating the same.

In the drawings like letters of reference inl .iO dcate corresponding parts in each figure.

A is the main frame of the machine.

B is themain drivingshaft, suitably journaled in the frame A, and provided with a balance-wheel, G. This shaft is propelled by any suitable motor, and has attached to it al the cams necessary to produce the different lmotions in the machine; but as my invention relates only to that portion o'f the machine 1.

Patented in England January 30, 1884, No 2,409.

which gums and places the blanks on the carriers it will4 not be -necessary in this specification to explain the various motions produced by the revolving of the drivingfshaft B. It will be sufficient for my purpose to vshow the connection between this shaft and the parts involved in my invention.

D is a rock-shaft, one arm of which is connected by link D and cross-head D2, as shown in Figs. 2 and l0, to the spindle E ofthe vertically-operating picker F. The outer end of this rock-shaft D is connected by a pitm'an, G, to one-branch of abifurcated arm, H,which is pivoted on the frame A, the other branch of the said arm beingprovided with africtionroller, a, situated immediately below the end of the pitman G, and arranged to rest upon the cani I, which is keyed or otherwise fastened to the shaft B. Thus when this shaft revolves the cam I acts againstk the friction-roller a, which in following the form of thecam I imparts a rocking movement to the rock-shaft D (see Figs. .6 and 10) and through it causes the picker or gummer F (see Figs. 2 and l0) to rise and fall, as vand for the purpose hereinafter more particularly explained.v

A The other end of the driving-shaft B has attached to it a cam, J, (see Figs. 8 and 10,) which is arranged to act against the frictionroller b. This roller is attached to a pitman, K, which connects with an arm of the rockshaft L. The other arm of this rockshaft L has hinged to it the bar M,- (see Figs. 2 and l0,') the other end of which is connected to `and isl designed to support the auxiliary gummer N. The cams I and J are so set on the shaft B that whenthe cam I has thrown the picker- F the full length of its downward stroke the cam vJ has caused, through'its connections, the auxiliary gummerl to reach and act upon the top blank, as hereinafter exi plained. Aspring, O, attached tothe pitm'an 9o K,holds the frictionroller b against the cam J.

I represents the pilev of blanks, andQ. the

nin-dish, locatedimmediately' above the pile lof blanks. .(See Figs. l and 2.)

R is agumming-roller, suitably journaled 95 within' the gumming-dish Q and caused to reattached to it.

volve, so that its upper surfacershall travel away from the edge of the gum-dish next to the picker F.

c is a scraper pivoted within the gum-dish V, located in front 'of the pile of blanks, and which Imay be provided with any well-known means of adjustment for regulating the amount of gum carried up by the roller; but as such means form no part of my invention, it is unnecessary to describe. them here. Owing to the direction in which the roller W revolves, the scraper c removes from the said roller any fiber which may thave adhered to the gumming-roller when the distributingroller last touched it. A clean surface on the gummingroller is thereby insured.

The distributing-roller S is carried in suitable guide-blocks, e, supported by the horizontal rods T. These rods T extend from the gum-dish Q to a point beyondthe back of the picker F, and are at such a' distance apart that the said picker works freely between them U is a rock-shaft, suitably journale'd. in

brackets attached to the main frame A' and located immediately above the gumdish Q.

This rock-shaft'is 4provided with arms f, connected to the links f', attached to the' guideblocks e, and an arm, g, having a pitmau, h, The lower end of this pitman is bifurcate'd to t over the shaft B, *and is pro'- vided with a friction-roller, i, larranged'to come in contact witlithe eccentric i,'which is keyed or otherwise fastened to the said shaft Bv. (See Fig. 7.) f The spring lathe lower end of which is attached to the frame A, keeps the frictionroller against the cam j. The cam j is so set -on the shaft B'that when the cam I, attached to the same shaft, has thrown the picker F to the full extentof'its upward stroke, the cam- 44o j has, through its connection with the distributing-roller S, as already described, thrown the said distributing-roller across the' plane of the picker F, the said picker being at this period in such a position that the distribut- Y. ing-roller S comes in contact with itsbottom short andquick. Gum is appliedtoithevbottom surface of the picker duringfthe'short period that it takes to change 'its upward' into a lvdownward` movement.

Q is a gum-dish (see Figs.' 1 and' ,eyieeedimmediately over the pile of blanks, and containing the gumming-roller R,wh,ich is caused to revolve in the same direction as the guniming-roller W,-and is also provided -with:a scraper, c, which scrapes the'roller R inthe v same manner as thel other scraper acts on thev roller W.

'Having now described the general'constru'ctien of the parts of` thelniachine involved in my invention, I shall proceed .to describe ,briey theoperation of that portion of the machine to whichmyinvention relates. ,n n

e Y serias The pileof blanks P is carried in an lelevator operated and constructed in the Yusual man.-

ner, except that the front guide-posts, X,

are provided with spring-.wires l, designed to hold the top *blank tightly against .the back guide-posts, in order t-o insure that the top blank shall always be in aposition to receivel the gum from 'the picker. When the picker F has Vreceived gum from the distributing-roller S, it immediately descends upon the pile of blanks P, gumming the back flapv-efwthe top Y spring permit the pitman Gto descend after the downward movement of the picker F has been arrested by coming incontact with 'the V pile of blanks.

(SeeFifgs. 6 and 10.) When thus descending,thegpitlnan G,being connect ed, as described, bythe spring nto the arm of the rock-shaftD, a, pressure is imparted upon the pile of blanks 'by the pickerF suiciently strong to hold the blanks during the period that t-he auxiliary gummer N performs ,its lfunction, but withoutharresting the motion of the shaft B.` After applyinggum to the sealap of the blank the lauxiliary lglimmer N is by' the action of its cam J thrown backinto contact .with the gumming-roller 'After' passing over the top surface of this gummingrollerlW the pinlo, which is attached l.to the bar -M, has been carried past the vback end of the vcurved bridge Vhen' the auxiliary gummer N is caused by its cam J to. ravelto- .ward the pile'of blanks,the pin o mounts the bridge p, thereby carrying with it the auxili-l ary' gummerN, keeping it clear jof a the guinming-roller NV, and raising it to a point above the top of the pile of blanks. The inner-end of the bridge p is at such apoint that thpicker F has rested 'suiiciently long onthe' f pile of blanks Ato allow the auxiliary gummer N tol apply gum to the seal-flap ofthe top;blank, its cam I causes it to ascend, the

um on the bottom surface of the picker causing the tep .blank to adhere to 4the4 picker, 4

which thereby carries the top blankl su- .ciently high to permit the carrier V to pass'y below it. (See'FiglfQ.)

As'I claim nothing in the operation of these' carriers, and as thelnoperation will be well understood by those skilled in envelope-maf chines, it isnot necessary to show or describe and as the pin ojalls the mechanism for-operating them; but in order to insure the easy delivery of the top l impart a gentle yet positive elasticforce against the blank, causing it to descend onto the carriers, as desired.

I am aware of the patent to Swift and Swift, No. 173,870, and make no claim to the construction shown therein as forming a part of my invention, as the glimmer or picker was not designed to forni a lioldfast for the blank while the auxiliary gummer is gulnming its seal-flap, this function being performed by a stencil-plate attached to the guides carrying the auxiliary gummer. By my. construction and arrangement the main glimmer performs the function' of a lioldfast for the blank while the auxiliarygummcr is carried over the sealrlap of the blank, dropped onto the same, and

drawn therefrom, thereby doing away with any intermediate device for holding theblank during the gumming of its seal-flap.

Vhat I claim as my invention is- 1. In an envelope-machine, the vertieallyreciprocating picker arranged to gum and raise one side of the top blank, in combination with the reciprocating auxiliary gummer constructed to fall directly upon the edge of the seal-flap, and mechanism, substantially as described, for drawing said auxiliary gummer off the flap While the picker is resting on the blank, as set forth.

2. The gumdish Q, located immediately over the pile of blanks, and the vertically-reciprocating picker supplied with gum from said gum-dish and arranged to carry the gum to one iiap of the blanks, in combination `with the second gum-dish located infront of the pile of blanks and provided with a gum-supplying surface, as W, on a level With the upper blank, and an auxiliary gummer arranged to be carried from said gum-dish to a point directly over the seal-flap of the blank and dropped thereon, and then drawn therefrom in a hori- Vzontal plane while the said picker is restingV upon and holding the blank, substantially as i described. v

3. In an envelope-machine having a gumming-dish located over the pile of blanks, a verticallyreciprocating picker arranged to gum and pick up one side of the top blank Slifficiently high to permit the carriers to pass below it, in combination with a spring-nger or fingers placed on the bottom of the gumdish, so that the blank carried up against it by the picker is pushed off the picker onto the carriers with a positive yet gentle elastic force.

4. In an envelope-machine, the verticallyreciprocating glimmer arranged to gum one side of the top blank, in combination with the auxiliary reciprocating gummer for gumming the seal-flap, and mechanism, substantially as described, constructed to' carry said gummer from the gum-dish tothe edge of said flap, and then lower it directly upon the same and draw it off while the gummer is resting on theblanks,

substantially as set forth.

5. In an envelope-machine havingla gumdish located over the pile of blanks, the vertically-reciprocating picker constructed and arranged to gum and raise one side of the top blank, and the roller arranged to convey the gum from the gum-dish to the under sideof the picker, in combination with the reciprocating auxiliary gumnier, the second' gum-dish located near another edge of the blank and carrying a roller Whose upper surfacejs substantially on' a level with the top blank, and mechanism, substantially as described, for carrying said auxiliary gummer over thev edge of the blank and free from contact with the same,

and then' dropping said glimmer upon the blank and-drawing it therefrom in a horizontal position while thepicker is resting on the other edge, asset forth.
